Model number:
YS-017 Peony Root Bark Extract
Overview. YaoSynBio Peony Root Bark Extract is a high-performance liquid active derived from the dried root bark of Paeonia suffruticosa — known in traditional Chinese medicine as Moutan Cortex. Using a controlled enzyme-hydrolysis process instead of harsh solvent extraction, the ingredient preserves and mobilizes the root bark's signature actives, producing a clear, pale-yellow liquid (pH 4.0–5.5) designed for advanced whitening and anti-aging formulations.
Mechanism. Enzymatic hydrolysis raises bioavailable flavonoids by 24.1% and polyphenols by 18.4%. The extract directly inhibits tyrosinase and DOPA oxidase, two key enzymes in the melanin synthesis cascade, thereby reducing hyperpigmentation at its source. It also modulates the MAPK/AP-1 signaling pathway, dampening UV-induced inflammatory and photo-aging responses. Naturally containing 70+ amino acids and 50+ unsaturated fatty acids alongside paeonol, it combines melanin suppression with antioxidant and skin-barrier supportive activity.
Applications. Recommended at 2%–5%, the extract is ideal for whitening serums, spot-correction essences, anti-pigmentation creams, after-sun soothing products, and comprehensive anti-aging lines. Its multi-target action on melanin enzymes and photo-aging pathways makes it a strong natural alternative to synthetic brighteners. The ingredient is listed in EU CosIng and compliant with EC 1223/2009, FDA-compliant for cosmetic use, and compliant with Chinese cosmetic regulations for worldwide market access.
